Lite3DP is a micro 3D printer that uses high print quality, virtually silent MSLA technology. It is the first of its kind to be completely Arduino-based, is open source, and comes in an easy-to-assemble kit format. It is a simple machine designed for experimentation to provide an in-depth and complete understanding of its operation. It can be placed on almost any table or in any workshop. MSLA resin 3D printing technology can achieve stunning levels of detail and surface finishes that are far superior to what can be achieved with filament 3D printers – primarily by using screen-cured resins such as LCDs on Lite3DP. Although 3D printers with MSLA technology are already available at similar prices to filament printers, they are closed-source projects that eschew one of the most valuable features of modern 3D printing - accessibility.
Inkplate 10 is a powerful, energy-efficient, Wi-Fi-enabled ESP32 development board with a recyclable 9.7-inch e-paper display. It's open hardware supported by open source software libraries, and it's easy to program whether you prefer MicroPython or the Arduino IDE.

The RoverWing is an expansion board (or "wing", following Adafruit's terminology) for the Adafruit Feather board that provides motor drivers that can handle 6-12 V motors, an inertial motion unit (IMU), and common servos, acoustics, etc. for mobile robots. Connectivity ports for GPS, GPS and other peripherals. Affordable, with powerful Arduino libraries and excellent documentation. It also contains a microcontroller with preloaded firmware to control these peripherals, which communicates with the Feather board using the I²C protocol, thereby freeing up the Feather board's resources for other uses.
Neurostimulation involves the application of short electrical pulses to the surface of the skin to stimulate underlying nerves and muscles. In recent decades, neurostimulation has been used as part of functional electrical stimulation (FES) therapy to help restore movement to muscles in paralyzed limbs in stroke patients and people with spinal cord injuries. While conducting research in areas such as pain relief and sensory feedback, scientists also use neurostimulation to study the effects of electrical current on neurons. Historically, the delivery of neurostimulation has required the purchase of expensive research-grade equipment or costly, time-consuming custom hardware constructs. NeuroStimDuino provides an open source alternative in the form of an Arduino shield.
PiMod Zero brings old technology back to life by allowing the Raspberry Pi Zero to display color or black-and-white video and play audio on vintage TV sets. It provides a super compact way to watch old movies, play retro games, display digital art or browse using any TV operating system that receives standard NTSC broadcasts on VHF channels 2 and 3 (55.25 MHz and 61.25 MHz).
Stereo Mic and Speaker HAT is an audio HAT for the Raspberry Pi board with dual speakers and microphones for stereo audio playback and recording. HAT does not need to be installed as the onboard EEPROM dynamically loads device tree overlays. First, all you need to do is plug in the HAT and boot up the Pi. Make sure not to plug or unplug the HAT while the Pi is powered on and running, but really, it's that simple! By default the amplifier gain is +9dB, but the amplifier gain can be changed via the onboard pads by adding a small amount of solder. The compact HAT measures 65mmx30mm, which is the same size as the Pi Zero, Adafruit's bonnet HAT and Pimoroni's pHAT, making it easy to use the HAT for a variety of projects.
ANAVI Gardening uHAT is a low-cost, open-source Raspberry Pi add-on board that helps you develop smart solutions for monitoring and growing plants. ANAVI Gardening uHAT supports multiple sensors for soil moisture, temperature, humidity, air pressure and light. Getting started is easy: Just plug it into your Raspberry Pi with your bare hands and follow the instructions in the user manual. No welding required and no tools required.
Pellicanus is an open source, RP2040-based INS/GNSS module that you can program using MicroPython, C or Rust.

Mico is a high-quality PDM to USB audio microphone based on the Raspberry Pi RP2040 chip. Most compact microphones available for embedded Linux systems such as the Raspberry Pi have high noise and low sensitivity. By pairing a high-quality PDM microphone with a standard USB audio output, Mico gives you an audio input platform that you can tailor to your needs. Mico is a great platform to learn and experiment with the RP2040 and digital audio. It can be used as a universal USB microphone for a Raspberry Pi, desktop or laptop computer. Mico can also be used as a high-quality USB audio input for embedded machine learning applications. Additionally, because TinyML supports RP2040, Mico can be used as a standalone edge computing audio device.
PlainDAQ is a simple, useful tool that adds basic precision analog functionality to your Raspberry Pi Pico board. It features a precision, low noise, low drift 12-bit 500k sps/s ADC. To match the ADC and maintain its noise and accuracy, all analog inputs are buffered and the ADC is driven by a high speed/low noise fully differential amplifier. It also has a 10-bit DAC that helps create analog outputs and waveforms.
